closed loop

I have been reefing for a little over a year now. I can not seem to keep coral happy but its ok; frustrating but slowly figuring it out. I purchased a red sea xxl750 v3 second hand (steal of a deal for the setup) and it has been good to me so far but ....... I keep seeing the failures so it's...

Any recommendations on GPH for a closed loop system? It has one 1.5" drain and four 1.5" return lines on the back wall of the tank. The display volume is 300 gallons. It has a sump with two overflows and four 1" return lines. Approximate head height is about 4.5 feet. I have the...

I have never plumbed a closed loop system before. Recently purchased a 300 gallon aquarium with 1.5" bulkheads on the returns. Having a difficult time deciding what the best way to connect the 3/4" loc-line. Any links, tips, info you can share? I haven't purchased and loc-line or adapters just...

Hello everyone. I currently have an 8-watt UV sterilizer hard plumbed from my sump to my DT, acting as a secondary pump to the DT, along with a direct line from a Cor pump. After reading more, I understand it's better to have a closed loop from the DT directly back to the DT. How important is...

Hello everyone, just set my new aquarium on its stand and I'm starting to rough out a plumbing design. We've just received a Planet 310 that I'd added a couple of extra holes for 1" bulkheads in the back glass to feed a closed loop UV system. I've got a Aqua UV Classic 80 watt unit that was...

I have a general "how to" that requires someone with experience since I've only used closed loops with an Iwaki in a 50gal. I have one closed loop plumbed on a 150g tank (5ft x 2ft x2 ft and on one side I will have a 1" "spray bar" type setup that houses 2 random flow generators with eductors...

The VCA 134-Gallon Cube - Random Flow Generator Powered Mixed Reef! The first of two new offices tanks are officially under way, and I can’t wait to share it here on Reef-2-Reef Our goal with this tank is to build a mixed reef tank with a unique flow solution that utilizes just Random Flow...

Hey R2R, I primarily read through my local reef forum. However I wanted to make my build thread here to get a broader range of inputs on what I’m doing. I’ll likely stick to my plans but it’s always good to hear other opinions. I grew up with a reef tank in my house, but never dealt with its...

I’m getting ready to do a closed loop on a massive reef tank. This tank is 20’ long by 4’ wide. I drew up a diagram on the computer of how I’m thinking it should be, hopefully you can understand it. I wrote next to everything to tell what it is. If you see anything you would change please let me...

Hello, I am about to start a new build. I was able to get a tank second hand that fits perfectly in my house. It is drilled for a closed loop style to go with a standard overflow sump filtration. This excites me as I don’t like the look of any cords or equipment in my display including...

Hey all, I am planning my next tank build. It will be a 340 gallon tank (130"x24"x25"). I am going to do 4 separate closed loops. Ill attach the picture. each color is a seperate closed loop being run by either an ecotech vectra L1 or a Reef Octo Varios-8. Im not sure which pump to go with. I...

Hi hoping some of you can help me decide on the placement and size of the holes/piping for the closed loop I want to run on my new Peninsula tank. It is a 7x3x2 ft tank and i don't want any wavemakers on the viewing panes so going to run a closed loop. I am happy to have wavemakers on the weir...

Hello everyone. I should have done this a while ago as no matter how many threads or videos you read and watch, nothing prepares you for the real thing. Here is my story. A little over a year ago I decided that I wanted to get back into the hobby, so I started researching, reading and watching...

So, I purchased a tank recently with a internal overflow. I have a Synergy overflow on my other reef I plan to install on the new reef. As I was contemplating how to plug up the holes in the bottom after removing the internal overflow, an idea came to me. Why not turn the existing holes into...
